Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments, and all other embodiments obtained by those skilled in the art without making any inventive effort based on the embodiments of the present invention are within the scope of protection of the present invention.
Fig. 1 is a flowchart of a message sequence processing method in protocol simulation according to an embodiment of the present invention, and as shown in fig. 1, the method may include the following steps:
step 101, obtaining at least two message sequences;
102, processing each message sequence according to a preset rule to trigger at least one target event;
step 103, determining callback functions corresponding to each target event;
step 104, completing the target event by calling a callback function.
In an embodiment of the present invention, by obtaining at least two message sequences, for each of the message sequences, performing: processing the message sequence according to a preset rule to trigger at least one target event, wherein the target event is used for representing the processing operation of the message sequence; determining a callback function corresponding to each target event, wherein the preset rule comprises a corresponding relation between the target event and the callback function, and the callback function is used for representing and executing processing operation corresponding to the target event; and completing the target event by calling a callback function. All processing operations needing to be waited, which are involved in the running process of each message sequence, are related to each message sequence by triggering an event corresponding to the processing operation, calling a callback function to execute the processing operation corresponding to the event, reducing the waiting time and the occupied space of CPU resources, so that a protocol can be processed simultaneously to simulate a larger number of message sequences, and the larger number of message sequences processed in the same time by the protocol simulation is indicative of higher efficiency of the protocol simulation. Therefore, the method realizes the protocol simulation process of massive concurrency of the message sequences through event driving, and improves the processing efficiency of the message sequences in the protocol simulation.
Optionally, as shown in fig. 1, a method for processing a message sequence in protocol emulation, in step 102, the message sequence is processed according to a preset rule to trigger at least one target event, which may be specifically implemented by the following ways:
determining the running state of the message sequence according to a preset rule, wherein the running state comprises at least one of initiating connection establishment, initiating reception and initiating connection closing;
triggering a first target event when determining that the running state of the message sequence is that connection establishment is initiated, wherein the first target event is used for representing processing operation for establishing connection to the message sequence;
triggering a second target event when the running state of the message sequence is determined to be the initiation of receiving, wherein the second target event is used for representing the processing operation of receiving the message sequence;
and triggering a third target event when the running state of the message sequence is determined to be the initiation of closing the connection, wherein the third target event is used for representing the processing operation of closing the connection on the message sequence.
In the embodiment of the invention, the running state of the message sequence is determined by monitoring the message sequence in the protocol simulation, and the target event corresponding to the running state is triggered according to the running state of the message sequence. Triggering a first target event for establishing connection of the message sequence when the running state of the message sequence is initiation of connection establishment; when the running state of the message sequence is that the receiving is initiated, triggering a second target event for the message sequence to receive the message; when the running state of the message sequence is that the connection is initiated to be closed, a third target event is triggered for the message sequence to close the connection. Therefore, in the protocol simulation process of the message sequence, according to the running state of the message sequence, triggering a target event corresponding to the running state, and completing the target event without waiting in a blocking mode or querying in a non-blocking mode, so that the waiting time of the message sequence is reduced, and the efficient running of a single message sequence in the protocol simulation is achieved.
In the embodiment of the invention, the message sequence is processed according to the preset rule, so that one target event can be triggered, and a plurality of target events can be triggered.
Optionally, as shown in fig. 1, a method for processing a message sequence in a protocol simulation, determining a callback function corresponding to each target event in step 103 may be specifically implemented by the following manner:
determining a first callback function corresponding to the first target event according to the corresponding relation in the preset rule;
determining a second callback function corresponding to the second target event according to the corresponding relation in the preset rule;
and determining a third callback function corresponding to the third target event according to the corresponding relation in the preset rule.
In the embodiment of the invention, the preset rule comprises the corresponding relation between the target event and the callback function, specifically: the first callback function is used for executing processing operation corresponding to the first target event, the second callback function is used for executing processing operation corresponding to the second target event, and the third callback function is used for executing processing operation corresponding to the third target event. Each message sequence has three running states of initiating connection establishment, initiating receiving and initiating connection closing, and the running states of initiating connection establishment, initiating receiving and initiating connection closing correspond to three target events of connection establishment, receiving and connection closing respectively. For three target events, three callback functions are acquired and used for executing processing operation corresponding to each target event, continuity of message sequence execution in the running process of the message sequence is guaranteed, time waiting for connection establishment, waiting for receiving or waiting for connection closing is reduced, and processing efficiency of the message sequence is improved.
In the embodiment of the invention, the callback function can be obtained directly from a callback function library which is built in advance, or the callback function corresponding to the target event can be created.
Optionally, the message sequence processing method in the protocol emulation as shown in fig. 1, after completing the target event through the callback function in step 104, further includes:
invoking the first callback function corresponding to the first target event, and feeding back a first signal, wherein the first signal is used for representing that the first target event is completed;
switching the running state of the message sequence to initiate reception according to the first signal;
invoking the second callback function corresponding to the second target event, and feeding back a second signal, wherein the second signal is used for representing that the second target event is completed;
switching the running state of the message sequence to initiate closing connection according to the second signal;
and calling the third callback function corresponding to the third target event, and feeding back a third signal, wherein the third signal is used for representing that the third target event is completed.
In the embodiment of the invention, a single message sequence is sequentially executed in protocol simulation, namely when the message sequence is in an operation state of initiating connection establishment, a first target event for establishing connection is triggered, a first callback function for executing connection establishment is called, and a first signal for indicating that connection establishment is completed is fed back; at the moment, according to the first signal, the running state of the message sequence is switched to initiate receiving, when the message sequence is in the running state for initiating receiving, a second target event for receiving is triggered, a second callback function for executing receiving is called, and a second signal for indicating that the receiving is completed is fed back; at this time, according to the second signal, the running state of the message sequence is switched to the connection closing state, when the message sequence is in the connection closing running state, a third target event for closing the connection is triggered, a third callback function for executing the connection closing is called, and a third signal for indicating that the connection closing is completed is fed back. When the third signal is received, then it is determined that the current message sequence completes the test. Thus, when the message sequence sequentially triggers three target events, the message sequence sequentially executes the three target events in sequence, the existence of the feedback signal ensures the sequential execution of a single message sequence, and the waiting of the message sequence in the protocol simulation test is avoided, so that the occupation space of CPU resources of the single message sequence is reduced.
Optionally, the message sequence processing method in the protocol emulation as shown in fig. 1, after completing the target event through the callback function in step 104, further includes:
counting the number of the message sequences completing each target event within a preset time length, and determining the number as the completion number;
judging whether the number of completed products is larger than a preset number threshold value or not;
and if the number of completed protocol simulation is greater than the preset number threshold, determining that the protocol simulation is completed.
In the embodiment of the invention, the number of message sequences of all target events is counted and the relation between the number and the preset number is compared, and when the number is larger than the threshold value of the preset number, the completion of the protocol simulation is determined. The preset number may be the number of message sequences tested by adopting the prior art method within a preset time period, or may be an expected value for completing the message sequences for the protocol simulation. Therefore, the high efficiency of the protocol simulation can be further determined by comparing the number of the message sequences for completing each target event within the preset time length with the preset number, and the result of the protocol simulation can be more intuitively displayed to the user.
As shown in fig. 2, in order to more clearly illustrate the technical solution and advantages of the present invention, the following details of a message sequence processing method in protocol simulation provided by the embodiment of the present invention specifically include the following steps:
step 201, at least two message sequences are acquired.
In this step, a preset duration of protocol simulation is set, a set number of message sequences of the required protocol simulation is determined, and the message sequences of the set number are acquired for the protocol simulation.
For example, the preset duration is m seconds, the set number is n tens of thousands, and n tens of thousands of message sequences are acquired for protocol simulation.
Step 202, determining the running state of the message sequence according to a preset rule, and executing step 203 if the running state is determined to be the initiation of connection establishment; if it is determined that the running state is to initiate reception, step 206 is executed; if it is determined that the running state is to close the connection, step 209 is performed.
In this step, the running state of the message sequence is determined by listening to the message sequence in the protocol emulation. The method comprises the following steps: when the running state of the message sequence is monitored to initiate connection establishment, acquiring an output parameter initiating connection establishment, analyzing the output parameter to obtain an analysis parameter, constructing an input parameter establishing connection based on the analysis parameter, and calling a functional interface socket corresponding to the connection establishment, namely a callback function, through event driving and the input parameter establishing connection so as to complete connection establishment of the message sequence. Similarly, when the running state of the monitored message sequence is the initiation of receiving, the message sequence is received by the method, and when the running state of the monitored message sequence is the initiation of closing the connection, the closing of the message sequence is completed by the method. Therefore, in the protocol simulation process of the message sequence, according to the running state of the message sequence, triggering a target event corresponding to the running state, and reducing the waiting time of the message sequence so as to achieve the efficient running of a single message sequence in the protocol simulation.
Step 203, triggering a first target event, and determining a first callback function corresponding to the first target event according to the corresponding relation in the preset rule.
In this step, when the running state of the message sequence is that connection establishment is initiated, the server sends a data segment with a flag bit of the synchronous sequence number to the client, requests connection establishment from the client, is used for indicating the intention of communication to the client, and informs the client to reply by using the target sequence number as the initial data segment. After receiving the request from the server, the client responds to the server with a data segment with an Acknowledgement (ACK) and a sync sequence number (Syn cookie, syn) flag bit, to inform the server that the data can be transmitted and can reply with the target sequence number as the initial data segment. And after receiving the data segment sent by the client, the server sends a confirmation response signal to the client, and at the moment, the server and the client complete 3-time handshake, trigger a protocol stack to establish a first target event of connection, and determine a first callback function for executing connection establishment according to the corresponding relation between the first target event and the first callback function in a preset rule.
Step 204, a first callback function is called, and a first signal is fed back.
In this step, an output parameter initiating connection establishment is obtained, the output parameter is analyzed to obtain an analysis parameter, an input parameter establishing connection is constructed based on the analysis parameter, a functional interface socket corresponding to the connection establishment is called through event driving and the input parameter establishing connection, namely a first callback function, so that connection establishment of a message sequence is completed, and a first signal that connection establishment is completed through the message sequence is fed back.
Step 205, switching the operation state of the message sequence to initiate reception according to the first signal, and executing step 206.
In this step, since the first signal indicates that the message sequence has completed establishing a connection, at this time, according to the message execution sequence of the message sequence, the running state of the message sequence is switched to initiate reception, so as to ensure the continuity of the message execution of the message sequence, reduce the unnecessary waiting time of the message protocol, and reduce the occupation space of the CPU resource of the message sequence as much as possible.
And 206, triggering a second target event, and determining a second callback function corresponding to the second target event according to the corresponding relation in the preset rule.
In this step, when the running state of the message sequence is that the receiving is initiated, a second target event of the protocol stack for establishing connection is triggered, and a second callback function for executing the receiving is determined according to the corresponding relationship between the second target event and the second callback function in the preset rule.
Step 207, call a second callback function and feed back a second signal.
In the step, the output parameters which initiate the receiving are acquired, the output parameters are analyzed to obtain the analysis parameters, the received input parameters are constructed based on the analysis parameters, the function interface socket corresponding to the receiving is called through event driving and the received input parameters, namely the second callback function, so that the receiving of the message sequence is completed, and the completed second signal is fed back to the receiving of the message sequence.
Step 208, according to the second signal, the running state of the message sequence is switched to initiate receiving, and step 209 is executed.
In this step, since the second signal indicates that the message sequence has been received, at this time, according to the message execution sequence of the message sequence, the running state of the message sequence is switched to initiate closing connection, so as to ensure continuity of message execution of the message sequence, reduce unnecessary waiting time of the message protocol, and reduce occupation space of CPU resources of the message sequence as much as possible.
And step 209, triggering a third target event, and determining a third callback function corresponding to the third target event according to the corresponding relation in the preset rule.
In this step, when the running state of the message sequence is that the connection is initiated to be closed, the server sends a request for stopping the TCP connection to the client, the control bit FIN is set to 1, after the client receives the state that the control bit FIN is 1, the TCP in the connection direction is confirmed to close the connection, the ACK is set to 1, the server puts forward the TCP connection request in the opposite connection direction to the client again, the control bit FIN is set to 1, the client confirms the request sent by the server, the ACK is set to 1, at this time, the client and the server complete 4 handshakes, a third target event for closing the connection by the protocol stack is triggered, and a third callback function for executing the connection is determined according to the corresponding relation between the third target event and the third callback function in the preset rule.
Step 210, call a third callback function and feed back a third signal.
In this step, an output parameter initiating closing connection is obtained, the output parameter is parsed to obtain a parsing parameter, an input parameter of closing connection is constructed based on the parsing parameter, a function interface socket corresponding to closing connection, namely a third callback function, is called through the input parameter of event-driven and closing connection to complete closing connection of a message sequence, and a third signal that closing connection of the message sequence is completed is fed back.
Step 211, switching the running state of the message sequence to initiate closing connection according to the third signal.
In this step, since the third signal indicates that the message sequence has completed closing the connection, at this time, according to the message execution sequence of the message sequence, the running state of the message sequence is switched to closing the reception, so as to ensure the continuity of the message execution of the message sequence, reduce the unnecessary waiting time of the message protocol, and reduce the occupation space of the CPU resource of the message sequence as much as possible.
Step 212, counting the number of message sequences for completing the third target event within the preset time period, and if the number is greater than a preset number threshold, determining that the protocol simulation is efficient.
In this step, the judging basis of the protocol simulation efficiency may be that the number of the message sequences completing the test within the preset time period reaches a preset number, where the preset number may be the number of the message sequences completing the test within the preset time period by using the prior art method.

In summary, the method and the device for processing the message sequence in the protocol simulation provided by the embodiments of the present invention have at least the following beneficial effects:
1. In an embodiment of the present invention, by obtaining at least two message sequences, for each of the message sequences, performing: processing the message sequence according to a preset rule to trigger at least one target event, wherein the target event is used for representing the processing operation of the message sequence; determining a callback function corresponding to each target event, wherein the preset rule comprises a corresponding relation between the target event and the callback function, and the callback function is used for representing and executing processing operation corresponding to the target event; and completing the target event by calling a callback function. All processing operations needing to be waited, which are involved in the running process of each message sequence, are related to each message sequence by triggering an event corresponding to the processing operation, calling a callback function to execute the processing operation corresponding to the event, reducing the waiting time and the occupied space of CPU resources, so that a protocol can be processed simultaneously to simulate a larger number of message sequences, and the larger number of message sequences processed in the same time by the protocol simulation is indicative of higher efficiency of the protocol simulation. Therefore, the method realizes the protocol simulation process of massive concurrency of the message sequences through event driving, improves the processing efficiency of the message sequences in the protocol simulation, and executes the following steps for each message sequence by acquiring at least two message sequences: processing the message sequence according to a preset rule to trigger at least one target event, wherein the target event is used for representing the processing operation of the message sequence; determining a callback function corresponding to each target event, wherein the preset rule comprises a corresponding relation between the target event and the callback function, and the callback function is used for representing and executing processing operation corresponding to the target event; and completing the target event by calling a callback function. All processing operations needing to be waited, which are involved in the running process of each message sequence, are related to each message sequence by triggering an event corresponding to the processing operation, calling a callback function to execute the processing operation corresponding to the event, reducing the waiting time and the occupation space of CPU resources so as to be convenient for concurrent protocol simulation of a larger number of message sequences, wherein the larger number of message sequences of the protocol simulation indicates that the protocol simulation is more efficient. Therefore, the invention realizes the protocol simulation process of massive concurrency of the message sequences through event driving, and improves the processing efficiency of the message sequences in the protocol simulation.
2. In the embodiment of the invention, the running state of the message sequence is determined by monitoring the message sequence in the protocol simulation, and the target event corresponding to the running state is triggered according to the running state of the message sequence. Triggering a first target event for establishing connection of the message sequence when the running state of the message sequence is initiation of connection establishment; when the running state of the message sequence is that the receiving is initiated, triggering a second target event for the message sequence to receive the message; when the running state of the message sequence is that the connection is initiated to be closed, a third target event is triggered for the message sequence to close the connection. Therefore, in the protocol simulation process of the message sequence, according to the running state of the message sequence, triggering a target event corresponding to the running state, and completing the target event without waiting in a blocking mode or querying in a non-blocking mode, so that the waiting time of the message sequence is reduced, and the efficient running of a single message sequence in the protocol simulation is achieved.
3. In the embodiment of the invention, the preset rule comprises the corresponding relation between the target event and the callback function, specifically: the first callback function is used for executing processing operation corresponding to the first target event, the second callback function is used for executing processing operation corresponding to the second target event, and the third callback function is used for executing processing operation corresponding to the third target event. Each message sequence has three running states of initiating connection establishment, initiating receiving and initiating connection closing, and the running states of initiating connection establishment, initiating receiving and initiating connection closing correspond to three target events of connection establishment, receiving and connection closing respectively. For three target events, three callback functions are acquired and used for executing processing operation corresponding to each target event, continuity of message sequence execution in the running process of the message sequence is guaranteed, time waiting for connection establishment, waiting for receiving or waiting for connection closing is reduced, and processing efficiency of the message sequence is improved.
4. In the embodiment of the invention, a single message sequence is sequentially executed in protocol simulation, namely when the message sequence is in an operation state of initiating connection establishment, a first target event for establishing connection is triggered, a first callback function for executing connection establishment is called, and a first signal for indicating that connection establishment is completed is fed back; at the moment, according to the first signal, the running state of the message sequence is switched to initiate receiving, when the message sequence is in the running state for initiating receiving, a second target event for receiving is triggered, a second callback function for executing receiving is called, and a second signal for indicating that the receiving is completed is fed back; at this time, according to the second signal, the running state of the message sequence is switched to the connection closing state, when the message sequence is in the connection closing running state, a third target event for closing the connection is triggered, a third callback function for executing the connection closing is called, and a third signal for indicating that the connection closing is completed is fed back. When the third signal is received, then it is determined that the current message sequence completes the test. Thus, when the message sequence sequentially triggers three target events, the message sequence sequentially executes the three target events in sequence, the existence of the feedback signal ensures the sequential execution of a single message sequence, and the waiting of the message sequence in the protocol simulation test is avoided, so that the occupation space of CPU resources of the single message sequence is reduced.
5. In the embodiment of the invention, the number of message sequences of all target events is counted and the relation between the number and the preset number is compared, and when the number is larger than the threshold value of the preset number, the completion of the protocol simulation is determined. The preset number may be the number of message sequences tested by adopting the prior art method within a preset time period, or may be an expected value for completing the message sequences for the protocol simulation. Therefore, the high efficiency of the protocol simulation can be further determined by comparing the number of the message sequences for completing each target event within the preset time length with the preset number, and the result of the protocol simulation can be more intuitively displayed to the user.
